How to change a C3 headlamp bulb?

After reading many comments, I must be lucky as I have been driving a C3 for over 5 years and 'touch wood', never yet had to change a bulb, until today. After struggling for over an hour I gave up. I have normal size hands, but guess Citroen employ children with small hands to do this type of job.

Will take back to dealer to do, but if they charge, I'll go elsewhere, and will never ever but a new car again without checking if it is simple task to change bulbs
